Push for new SA airport

A group of Adelaide and mid-north councils says a new airport will be vital to help cope with South Australia's mining boom.

It says that relocating the airport now at Parafield could be an option.

The group of seven councils from Salisbury to the Clare and Gilbert Valleys says a new airport is a priority and it is willing to explore all options.

MP Nick Champion says a wide local investigation would be needed before the Federal Government considered the idea.

"I'm not sure if there's a need for a new airport facility but the Salisbury Council is interested in perhaps relocating the Parafield Airport so that obviously ... in looking at that we might look at another location elsewhere," he said.
